Actually Maxim, I did have a problem with reCaptcha, when I hit the sound option it started up the QuickTime plug-in then Firefox crashed on me, im using Firefox on Windows XP and its version 2.0.0.11

Let me see...

Quicktime has a habit of associating itself with common internet audio formats such as .au etc. I'd be inclined to remove such associations from quicktime and let firefox handle the audio if its capable.

Funny you should say that djbass, I just opened up quicktime and got a C++ buffer overflow error, it then closed on me, hehehe.

Other then that Maxim, reCaptcha is cool.

Ah, Quicktime, it's like RealPlayer all over again :)

(Google: Real Alternative, Quicktime Alternative)

There is a potential flaw in the reCapcha system, the need to provide accessability.

The added audio option opens the possibility for a bot to easily bypass the check. I noticed they scramble parts of the audio to avoid this but our ability to filter out bad audio in software is far superior to being able to do OCR on scrambled images.

Well, at least the spam's stopped now.

I am not sure how the backend of the reCAPTCHA works, but to avoid dealign with bots using OCR, couldn't the images have groups of dots, and you could let the user know they have to type in the number od ots in each group? For instance:

.: . : ::

the user would enter 3124 and all would be well in the world. I am not sure if this is feasible if bots using OCR becomes a problem, but if it is, it might be a good alternative.

That would be ridiculously easy to do in software.

I see.

I just installed reCAPTCHA for registration. We've had approximately 100 bots signing up every day recently (yet somehow failing to post, thank goodness), this ought to be a major block for them now. It's certainly solved the guest posting problems.
